Technical Overview
2016 Black Douglas Sterling Imperial 400 Technical Analysis & Specification Breakdown
At the heart of the 2016 Black Douglas Sterling Imperial 400 prototype - concept model motorcycle, Black Douglas utilizes a 400 cc (24.4 cu in) air-cooled single cylinder, four-stroke layout.
Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,500 mm (59.1 in) wheelbase engineered for balanced agility and highway composure. The 9-liter (2.4 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 100 km/h (62 mph).
